About this dam

Merritt Millpond Dam

Merritt Millpond Dam, located in Sarecta, North Carolina, is a state-owned earth dam built in 1800 for the primary purpose of recreation. The dam stands at a structural height of 15 feet and has a hydraulic height of 7 feet, with a length of 700 feet. It serves the Goshen Swamp and provides a storage capacity of 54 acre-feet, with a maximum discharge of 79 cubic feet per second. Despite being a significant hazard potential structure, the dam's condition is currently not rated as of its last inspection in October 2015.

Water resource and climate enthusiasts will find Merritt Millpond Dam an intriguing structure due to its historical significance and recreational purpose. The dam offers a glimpse into early water management practices in the region and continues to serve as a recreational site for visitors. With its proximity to the Goshen Swamp and a storage capacity of 54 acre-feet, the dam plays a crucial role in managing water flow and providing a habitat for various species of wildlife in the area. While its hazard potential is significant, the dam's structural integrity and maintenance are vital aspects to ensure the safety and functionality of this important water resource.

As a state-regulated dam in Duplin County, North Carolina, Merritt Millpond Dam undergoes regular inspections to assess its condition and ensure compliance with safety standards. The dam's emergency action plan status, risk assessment, and management measures are currently not rated or available. With its historical significance, recreational value, and role in water management, Merritt Millpond Dam remains a fascinating structure for water resource and climate enthusiasts to explore and monitor for future developments in the region.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
Poor
A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.

FAQ

About Merritt Millpond Dam

Where does the data for Merritt Millpond Dam come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Significant hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
